Mia Farrow has admitted that she is unsure if former partner Woody Allen is actually the father of her son, Ronan. In a new interview, Farrow said that there is a possibility her ex-husband Frank Sinatra could be the boy's father.

"He is a big part of us, and we are blessed to have him in our lives," Nancy Sinatra Jr. told "Vanity Fair" as part of the interview.

When asked about her relationship with Frank Sinatra, Farrow admitted that he was the love of her life and "possibly" the father of Ronan. "We never really split up," she explained. No DNA tests have been done on the boy, but rumors have fueled speculation about Ronan's parentage since his birth.

Ronan graduated from Bard College with a double major in philosophy and biology by the time he was 15 and enrolled at Yale Law School, where he graduated at 21. Since then, he has served as special advisor to the State Department, focusing on youth issues in Afghanistan and Pakistan. He worked closely with Hillary Clinton and now works with former president Bill Clinton.

He considers himself lucky to have grown up in a diverse household, thanks to his mother's numerous adoptions and his travels abroad thanks to UNICEF and his time as a Rhodes Scholar.

"I grew up across the table from Moses, who has cerebral palsy, and next to my sister Quincy, born of a drug-addicted, inner-city mother, and Minh, who is blind," Ronan told "Vanity Fair." "I could never have understood what it means to grow up blind or with cerebral palsy. I saw problems and needs, so the next thing you think is: 'O.K., what are you going to do about it?'" he asked.
